The bottom end of the collecting box 51 is fixedly connected to a dust suction port 52 for absorbing dust outward. When the fan 3 is started to start exhausting, the air will first enter the collection box 51 through the dust suction port 52, and then enter the interior of the storage box 41, so that the dust on the surface of the object to be marked can be absorbed.

[0030] Reference Figure 1 - Figure 3 The collecting assembly 5 also includes a block 53 for breaking up the air. When the air passes through the inside of the collecting box 51, it will be blocked by the block 53 and forced to disperse, so that the surface utilization rate of the filter plate 43 can be improved. The front end of the block 53 is rotatably connected to a baffle 54 for closing the top opening of the collecting box 51. The right end of the baffle 54 is fixedly connected to a gear 55 for driving the baffle 54 to rotate. The gear 55 is rotatably connected to the right end of the collecting box 51. The baffle 54 can be driven to rotate by rotating the gear 55. The right end of the collecting box 51 is close to the bottom end of the gear 55 and is slidably connected to a rack 56 for driving the gear 55 to rotate. The rack 56 and the gear 55 are meshed with each other, and the rack 56 can be driven by moving the rack 56 left and right. The wheel 55 rotates, and the right end of the rack 56 is fixedly connected to a handle 57 for facilitating the operator to move the rack 56.

The fixed spring 46 will always push the card block 44 outward to prevent it from falling out of the card slot 45.

[0033] Working principle: When the device is operating normally, the fan 3 will drive the air to flow into the interior of the device, and the air will pass through the dust suction port 52 and the collection box 51 into the interior of the storage box 41. When the air passes through the interior of the storage box 41, the dust will be blocked by the filter plate 43 and stay on the rear end face of the filter plate 43. When the filter plate 43 is blocked due to excessive accumulation of dust on the surface, the air will push the filter plate 43 to move to the left. The movement of the filter plate 43 to the left will push the rubber block 411 and the connecting rod 48 to move it to the left. In this way, the operator can judge whether the filter plate 43 is blocked by observing the position of the connecting rod 48.

[0034] When dust cleaning is required, you can first hold the handle 57 and move the adjustment block 58 to disengage it from the adjustment slot 510, and then you can move the handle 57 to the left to drive the rack 56 to move to the left. The rack 56 moving to the left will drive the gear 55 to rotate, and the rotation of the gear 55 will drive the baffle 54 to rotate upward and close. At this time, you can release the adjustment block 58, and the adjustment spring 59 will push the adjustment block 58 to re-engage it in the adjustment slot 510, re-fix the rack 56, and then you can move the block 44 inward to drive it to move inward and disengage from the slot 45, and then you can move the cover 42 upward to remove it, and then you can clean the filter plate 43. By cleaning the filter plate 43, the device can always maintain a high dust removal capacity.
